A500 Rev 5 - which CPU/Storage upgrade?

Greetings folks!

"I grew up with the Atari 800 and ST", but have had an Amiga 500 for a little while (mostly storage), and an A1200 with the ACA1221 upgrade for games.

I want to warm up my A500 for WHDLoad and other fooling around with Classic BBSes, etc. For this 500 I have: the Commodore 512kb trap door ram expansion; Indivision VGA, and a ATX PSU. I also have both Go-Tek and real floppy drives (int and ext) available; I may use a bit of both.

I see there are a bunch of CPU expansions, I'd like an opinion on which route to go for WHDLoad / (with good compatibility) duty for games and other classic applications. Ones I'm thinking about (please add if appropriate) :

ACA500plus - Works with the Rev 5 board; would allow me to further improve speed with the ACA1221 later if I got another accelerator for the 1200; converts Trap door RAM Into ChipRAM (= 1 MB), 8MB Of FastRAM, has storage. But sits externally. Seems like "enough" for any OCS games I'd be playing; if I needed more performance I have a 1200.

TF 534/536 - 536 is still being worked on, but I'm willing to wait. 68030; storage; TF is awesome for open sourcing these; 534 seems a bit low on RAM but 536 definitely fixes this. I'm not sure about compatibility?

Classic520 - Sits external, but an OC 68020 with 8 MB of fast RAM should even run Frontier Elite well on the A500. I really like that it has both CF and SD slots.

Wicher 500 - 68000 @ 35-50 MHz with fast RAM is decent; upgradable RAM, both CF and IDE storage, Internal (= nice). Not sure if this works with WHDLoad (IComp.de mentions custom circuitry on the ACA500Plus).

I assume to get to 1MB of ChipRAM on the TF / Classic / Wicher boards requires a new Agnus and some modification to my circuit board, so that's a negative (but do-able) for me.
