Sounds great Phil :-) Actually spent some time just now trying to nut out the possibilities and I reckon it's not too bad. The heads on these donks have 2 x spare mounting holes either end, front/back. The custom PS pump mount is currently using the 2 x front ones but bolts could be removed and longer installed. I'm thinking along the lines of a 50mm x 8mm plate bolted each end with an 8mm plate bridge system over the rocker for dropping the alternator on top of maybe?
