I suppose there is always the possibility of getting an overly aggressive Angel,they are cichlids after all. But for the most part,I don't think you would have a problem with some guppies.
On a side note. The only problem I have had with Angels is keeping them as pairs. I know the one I have is a female because she laid eggs. The other one I had with her also laid eggs. The 2 did not get along after that. I took one to the pet store,and now keep her as a single. I noticed your stocking plans,just wanted to give my experience with keeping pairs,FWIW.
Thanks for this info I asked in the angel forum and others seemed to think that they would do okay together...maybe I'd better not risk it
I'd love to keep some guppies though
