Blew front main oil seal, repair, replace or upgrade?

I'm talking about just the engine here. I think the seal was probably weak anyway but what happened was got into the Vtec zone in 2nd, car bogged down slightly or felt like it missfired, pulled off the dual carriageway and oil light came on. Fortunately owning two cars came in handy, especially when my other car is a 3.0 turbo diesel, so was able to tow it home.
I was hoping it was the oil filter that came loose so changed that, refilled with oil and started it up again to find its clearly the front main seal which failed. However the car still ran and idled perfectly it just leaked oil heavily, basically I havn't killed the engine.
The engine has survived so my main question is really what to do now.
A) Replace the oil seal and all the other seals I can get to on this engine, which would be everything bar rear main seal AFAIK. I'd be doing it in situ. I know i'd be looking at doing at least a cambelt change in addition to swapping the seals for new but is there anything else I should do while its stripped down?
B) Source a H22A7 and fit that and get rid of my engine, i'd probably still do most of option A but i'd be doing it on a freestanding engine away from the car and just slot in the new motor. For this i'd source a complete accord as the sums just about make sense in terms of stuff I can still sell on vs what i'd want to keep from an accord. The engine in it doesnt match the VIN anyway and is of dubious origin. My car was the one that was running 260bhp at one point before the engine and gearbox found their way into a mk4 and mine got a mystery engine and gearbox.
C)Keep the mystery engine but in addition to option A go a bit deeper with it. So upgrading some things while everythings apart instead of just servicing it. Again i'd be looking for any suggestions of things I can bolt on or drop in while i'm working on the engine.
Further thoughts. A is only really viable if I can do it all in situ. If I have to remove the engine B becomes alot more attractive given I know preciciely sweet FA about the engine in it. My folder of paperwork relates to an engine it doesnt have.
