I will say, I do like the bright white doorways of the new board. Makes line of sight much easier to determine at a glance. However, the Paizo board is just beautiful and adds so much theme.
I wonder if I could alter the Paizo board doorways with the help of one of those White-Out rollers? Hmmm.
Do you happen to have access to a scanner? If you could get some high resolution scans of the board I'm experienced at using Photoshop so should able to digitally modify it to match the new layout. This could then be printed and made into a new board. Sadly I don't own the Paizo edition or I'd scan it myself.
PM me if you're interested and I'll guide you on getting suitable scans.
