There are some talented creative people within the PFS community who could work to replace the GM Shared Prep drive maps with ones of their own creation, similar to these threads where members commission or share their character portraits:
I have several sets of tokens for scenarios which I have prepped which are mostly generic and should be ok. These are tokens I use both for VTT and print out to use physically.
Is there a compilation of which NPC portraits have been put in the blog? Otherwise I'll just double check and change all of the Paizo art for other pictures.
I'd take a crack at some maps, but I have no idea where the "substantially similar" line is and I don't want to waste a bunch of time only to find out that it does not comply with the license restrictions in the end.
