EZ-Spare Fit in Frunk

I hope one of the knowledgeable people here can help me.
My requirement is for a spare that will be safe for up to 500 miles at reasonable speed (70ish). I often drive from Austin to Santa Fe and would not want to spend days stranded between these waiting for tire/wheel replacements. From the threads here it would appear none of the frunk friendly offerings would be recommended, the Modern spare is probably closest.
I have a GT with 20 inch wheels. Would it be sensible to get a spare 20 inch wheel (not necessarily Lucid) fitted with a 245/40 tire? This would be the same size as existing for the front, but the rears are 265/40. Would there be a problem driving 500 miles on that mismatch at the rear?
Since I rarely use the frunk (I was put off by the hood bending issues on early Model S) I could put this up front for these long trips.
 
Just ordered mine, $375. Passed on their $50 cover; Amazon has several for less than $10
 
Anyone have any experience with this spare:

I have this one. Have I ever used it? no... I did get a portable ramp in case the car is too low to the ground to jack up.
 
Remind me how far these tires are recommended to drive…. I seem to recall it was not far, so wasn’t so sure it’d get me to a repair shop? Though I suppose it’d at least get me to a hotel where I could problem-solve.

(Pumping up a leaking tire has been all I’ve needed for decades now, so I’m reluctant to sacrifice that valuable frunk space)

But I’d appreciate hearing a more robust case for the value of these spares!!
