It's actually one of the times when WILD might be attempted with good chances. I'm not sure about it but SSILD might also be a good bet?

Then of course, you can just take a regular nap and put faith in your DILD encouragement throughout the day (since your chances are already much higher if you nap at a good time) and/or just do a little MILD routine. Simple quality meditation leading up to a nap also raises your chances by a lot in my experience.

I would say If you are really aiming to get that done napping, mix it out, don't limit yourself to one way.
