Glad you've got a working solution.Just to update this I ended up buying a pair of Boardman branded waterproof over trousers, mainly because I could try them on at the local Halfrauds (my legs are pretty long..) First use of them today in anger ie full rain and wetness on the commute, and they worked out well.
Thank you to everybody that contributed, I was very tempted by the rain legs but not sure I would have gained anything over the very light full waterproofs other than a few grams of weight?
I've got some Altura Night Vision ones. They are well made and have zipped calves and Velcro ankle cuffs. The fabric is quite heavy and they seem to be completely waterproof. They are pretty comfortable but totally uncool hipster wise. I was surprised at how rarely they are needed for my eleven mile round-trip commute. It doesn't seem to rain very often here in London.

I did the same, took the scissors to a cheapo pair of wps paired with some wp socks from Aldi, does the job without the boil in the bag effect.I turned a pair of full length cheapish w/p trousers into 3/4 lengths.
Much less hot to cycle in - but still keep thighs and knees dry - and no risk of lower end getting caught in chain.
And loads cheaper than dedicated cycling w/p's
Tights or whatever is underneath, can be pulled up to avoid the wet.
Wear waterproof socks - or change out of wet ones them when you get to your destination.
