On many Macs I've seen that supported 512k VRAM SIMM, it's almost always a single VRAM slot and next to a RAM slot. It seems if you design the board with through hole and mount the ZIP style RAM chips on the "back" side of the board instead of the typical front, it'd avoid clearance issue with existing RAM SIMMs?
Alternately make the VRAM SIMM board taller so the chips would be more than an inch higher than usual to clear most of the typical RAM SIMMs. It might be a problem in LC style box and other low profile housing. I haven't looked inside an all-in-one LC like 550 for many years, I can't remember what the clearance are like there.
Or are there Macintosh that can use 2x 512k? Could there be a 90-degree angled connector that would allow the ZIP style package to lie flat on the PCB and still keep the overall thickness from interferring with other components?
