Do you have a photo of the bike configured like you were riding it?
Measure the seat tube from the middle of the bottom bracket to...
I like to measure to the top of the top tube. But, some might measure to the top of the mast.
Like I said, start hunting for a good local welding shop that does aluminum. But, you could end up paying a couple hundred bucks for the repair, and it won't necessarily blend the paint perfectly. But, it could get you back on the road.
I can't say if it would be stronger or weaker than the original, or if other faults would eventually show up. With a long enough seat post, the mast failing like it did should be uncomfortable, but shouldn't cause a crash.
Obviously other failures like a dual headtube failure could be far more dangerous.
