I'd be very surprised if it was fixable from the bottom ... Very surprised!
The top is coming off, how far is yet to be determined.
I personally wouldn't even waste my time pulling the pan, I'd head right for the bank that has low comp and start pulling the head inspecting things as I go and stopping when I find the issue!
Yea, if it's a hole in the piston or broke piston you'll see it from the bottom, possibly even broken rings by seeing wall damage.
Is it noisy, have you listened with a stethoscope (screwdriver to your ear).
Broken rings and pistons can be heard if you know what you are listening for, they double clack.
For All I know it could just be a bad valve, but your comment about blow by indicates poor piston seal, not valves.
-Enjoy
