It's more involved than that. For example, let's say you had two MIDI streams 
doing running status (not uncommon, in fact it's the norm). If you blindly 
merged them, then both events would wind up going to the last non-running status 
message channel.

It really needs to be an active participant. It can't be done in discrete 
hardware itself (yeah, you could do it in an FPGA if you were absolutely crazy) 
- something (most likely a CPU with some MIDI knowledgeable code) needs to 
decode the stream and merge them.
