White Lisbon spring onions and pickling

I still have loads of onions which are bulbing fabulously at the moment and i am wondering whether they'd be allright to pickle? I have enough for two or three decent sized jars and although silverskin varieties are meant to be the one's to pickle, is there any obvious reason i couldn't use White Lisbons?

Any thoughts appreciated!!

They woud be fine, but are tricky to skin 

Thanks for the reply. How many layers need to come off or is it just the papery bit down the one side of the bulb...
