I am not sure is special treatment of subcases is good idea, because it requires extra effort for parsing.

FYI FriCAS produces result for all integrals (after expanding cases I got 86 integrals). Note: I did not check the results, for quick testing I joined split lines, removed '[', ',' ']' and all results. I needed to replace '#e' by '%e', after that FriCAS could parse your examples and with few macros understand them.
