Converting pics1 to Type 1

[Kittah]

I'm just curious if anyone has tried this - cutting and pasting the various tiles into appropriately-grouped sections in Type 1 format for ease of use on a new playerworld?

I've just started an attempt at it and the going isn't terribly slow, but neither is it terribly fast. I'm wondering if anyone has done it already, in which case it would be a fruitless endeavour...
