Doubtful - since each song has an internal name I'm assuming that the game's locations are hard coded to call up certain ones.
Thinking about it again, replacing the old ones, could probably be done with a lot of work. The MIDI.BSA file inside the \ARENA2 directory, containing all of the game's songs, has a fairly comprehensible structure. If I recall correctly, if you open it with a hex editor the songs literally just come one after the other, with their internal names before the instrument data. I don't know much about translating a MIDI file into hex, but if you just managed to find the bits of a song the BSA file uses and find their equivalents in an Arena MIDI, you could probably swap them out. Not sure how it'd work out, though.
