I think I have a few seed potatoes which have rotted in the cold and wet and so I have occassional gaps in my potato bed.

I could use up some seed potatoes which the allotment shed still have and have them come up later, but I also thought I could sow or plant a dozen or so peas and have them climb up a wigwam of stakes.

That way, if the gaps are just due to those seed potatoes being slower than the rest, I won't have a clash of seed potatoes growing in the same spot and the peas might actually grow through the potato canopy and give a double crop if they are tall enough in time.

Are there any other plants I could consider filling the gaps with?

I'd be getting my little 3-pronged fork out and having a look under the surface to see if the shoots are there - if the others are up they shouldn't be far behind.

If you don't find anything keep going until you do, it's the only way to be sure whether or not anything is going to come up there (your plans B and C seem a bit complicated otherwise.)

Good point - I'll go scrattin' as soon as I can. thanks
