Probably wouldn't be an issue in light air,but as a matter of safety,you might want to run backstays to the rear stanchions to support the load. There's info re this on the Macgregor Sailors site.
I was planning to raise the genoa 7 inches to clear the pulpit,and I had concern about the unsupported load on the upper mast,and running backstays was a possible remedy.
I will be adding a bowsprit for hanging an anchor,and moving the furler outside the pulpit instead.
As for being tender,once you get used to the boat heeling 10-15 as soon as your in the wind,it firms up well,and it's a non issue.
