Yes you definitely could,thats what im doing. With a quick weld to remount spring perches its almost bolt on. just decide if you want the longer gearing of the wt diffs first

can always change the centres anyway.
There is a bit more to it than that, those perches have to mounted in the right position to achieve the right pinion angle, cutting off the old ones is not that easy if you want to reuse them, otherwise you need to buy some mounts or cut them from another housing where you can cut the housing to waste and get them off neatly.
If you want to go chromo you need to fit a complete WT diff housings to the ront, upgrade to 26 spline front centre, fit a complete WT diff in rear as well, change tailshafts from 1 Litre to WT, change flanges on transfer to take the WT shafts, change steering arms to WT, lengthen front brake lines. As already mentioned by someone your diff ratios are also different.
Dont get confused between people talking about axles as compared to talking about housings. If you have a 1 litre front diff it has a smaller diff centre and housing tube size, you can either use 1 litre axles and cv's or you can upgrade and use 1300NT axles and cv's in your current diff housing.
