I have had almost the exact same project in mind for a long time, and now I may have some spare time to complete it. I want to use it to power several TDA7294 chip-amps, replacing the bulky linear regulated PSU that is being used now. I will publish everything since this is not a commercial project

That is great to hear since I will power 2x TDA7294 and 2x LM3886.
PS: Would 2x1000uF per rail be enough?
