1.7 engine is equally as easy just need the bell housing and ancillaries from the 1.7, i did this to my own one when i was 17, got the swap done and running in a day no problem with plenty hours to spare.
if you got the stuff minus the engine to swap to 1.7 you could fit a 1.8 16v out of a r19 or clio 16v just as easily
also to swap to b19, b200 and b230 will be pointless as you will have to replace the running gear also as 360's have different prop, bellhousing, loom etc as they are mostly injection so you would be cheaper and easier just buying a 360.
