That seems like a legit use, but no, it was determined to be too much of a performance hit.
A dedicated 'who has similar favs/upvotes to me' page seems like a good feature suggestion, since that would achieve a similar goal but without constantly hitting every post/show/12345 page render with the performance hit. It could even be limited with a 'X uses / month' type quota to be extra sure.

I guess a "show favorites" button in the post page could be a reasonable solution to unecessary usage.

I second Nathane here. The favorite lists of everyone who liked my drawings always brough some interesting stuff.
Are the programmers taking suggestions or still too busy fixing stuff?
