Even if you had a mill, you probably could not make that cut all the way

True. Could probably get closer than my router by angling the head.

Some one else suggested using a cold chisel which might be the best option
in your situation, although it might not look so pretty.

Other options could be:
1. Cut the sides off, then mill the slots, then screw, weld or braze back
together.

Too late for that. Originally was two parts and joined (with a backer bar)
where I'm now putting the slot.

Out of time, will reply to the rest this evening.

Do you have one of the many oscillating/multi-tools? Like this:

These cutters would probably cut aluminum okay (get extras):

Should look a bit better than chisel work, maybe...
