PRC doesn't include ACP but it has something like permanent merge - you will still need ACP haks but there should be no problems with running module with PRC and ACP.
If you check PRC site on the Vault you'll see that we have made merge haks for CEP 1, CEP 2 and Poject Q - no extra work for you

The hak order should look like this:
- PRC/CEP merge hak
- PRC haks
- CEP haks
- ACP haks
IIRC Grimoire uses HCR systems so it's not compatible with PRC. Anyway we have much more spells in PRC
