Two/ multipiece SB timing covers?

One of the Engine masters 360's had a chivy electric pump grafted onto a "dry" timing chain cover, I suppose you could cut an inspection window in the cover behind the electric water pump and get into it from there? What would be cool is a poor mans belt drive with an extension off the cam through a crank seal in the water pump well and a cogged lower hub on the crank. Maybe some sort of mechanical tensioner....

Gotta be cheaper than a Jesel or this 1500 RB unit:
