Use Ludicrous+ to precondition for CCS?

No, not at all. The battery is a huge thermal mass. It takes a lot of time of sustained conditioning to get it to the proper temperature. A few miles of heavy driving (even if you are actually driving like a madman) is not going to do much.

The OP isn't talking about spirited driving for a few miles before charging. They're talking about activating Ludicrous+ mode which causes the car to warm the battery pack to get it to optimal temperature for power transference. In theory, this should be similar to the preconditioning process that automatically occurs whenever you approach a Supercharger.

Gotcha. Well, I am unfamiliar with that mode, however, it still seems like more than a few miles would be necessary to condition the pack optimally.

That's basically the same thing the cars do to precondition the pack for optimal temp for Supercharging.
I should have specified that. I have the CCS adaptor and want to get the best use from it. I don’t think navigating to a nearby supercharger is for me, if there was one nearby I would probably just go there .

The preconditioning for Superchargers typically activates the last few miles before you arrive. I think it would help as any amount of pack heating is better than nothing.
preconditioning starts based on a calculation of how much time it will take to bring your pack from its current temp to the target, which might be as high as 50C (122F) or more. I can guarantee you it's more than "the last few miles" in Canada in winter 
Definitely not. There have been a lot of threads where people have been wondering how worth it this is, with the very very long times it runs preconditioning, using up a lot of energy, frequently for more than an hour.
Premature 'preconditioning battery for fast supercharging...?'
Anybody seeing super premature preconditioning? Typically precondition happens before 10/5 minutes of arrival of Supercharger. Recently I've seen it start to precondition -- on and off! -- at around 60 minutes / 60km away from Superchargers. All occurences were with battery already warmed...

Preconditioning for an hour??
I recently updated to 2021.4.11 and had need to travel from San Diego to LA, and set a supercharge stop about an hour away. As you can see in the attached photo, my car started preconditioning, even though I was 65 miles away from the charging station (nav was set to the L3 charger), and it was...

Preconditioning for fast charging, worth it?
Over the past couple of winter months, I have driven relatively long distances for skiing. In each case, the car has automatically put itself into the Preconditioning mode as my set navigation was to a Supercharger. While I understand the reasoning behind the preconditioning, I have also noticed...

I’ve never actually used my Ludicrous+ mode and probably never will except for pre-CCS if that turns out to be effective. I have seen DragTime youtubes where Plaid preheating takes him ~15-20 minutes, I wonder if Plaid heats to the same temp as L+, and if that is the same temp as navigating to SC heats the pack.
A one-touch Precondition icon on the nav screen seems acheivable, I’d trade fart sounds and other Elon crap for one.

On a trip in March 2021 my car started pre-conditioning for the Supercharger as soon as I left the house with 96% SOC, traveling to a Supercharger 182 miles away!

That's because you have a LR RWD, right? For pre-conditioning, a dual motor car uses the front motor to generate heat, and the rear motor to drive. On a RWD vehicle, since it's using the rear motor for locomotion, it tries to run it in an inefficient region to generate heat, but isn't able to generate much additional heat while you are moving.
