Double-crown forks for choppers

I'm planning on turning a junk frame I found into a chopper-type bike with forks about 3 feet long. Do I need double-crown forks, like these?

http://www.nsmb.com/images/gear/bighit%2003/boxxer.jpg

Obviously, mine won't be DH suspension forks like in the picture, but it's the fork crown I'm interested in.

My fear is that a single-crown fork won't be strong enough, as the longer fork legs are obviously going to act as levers and put a lot of stress on the crown. Is that likely to be an issue?

If I do need a double-crown, where could I get one in the UK?

I've taken the fork off a cheap (really cheap, as in thrown away/free) mtb, and extended the tubes.

One like this:

One of my junk-pile Huffy/Murray bikes had tubes that were the exact same width, just slugged them and welded on to the mtb fork tubes (leaving the suspension for bashing into curbs/children/poodles).
