If you are on a tight budget the S10 swap can be done pretty cheap but it is a lot of work. I think you could probably put the s10 front subframe on it and save some work but it won't lower the back as much as the S10 frame and the front track width is still a little too narrow. It depends what your goals are. They do make disc brake kits for the stock front axle if brakes are your main concern. I think Speedway has a kit for like $250.

For an idea of how much work the s10 swap is check out my build thread:
