Long bed body to blazer conversion

[Esetonni]

I don't know if I'm posting on the right section. I'm new to the cite. I have a 1970 gmc long bed, I've always loved how a lowered blazer without a top and with back seats looks like, with a little bit of free space on the back. Is it possible to use a long bed truck, get rid of the gap between the cab and bed, and pretty much convert it to a blazer look a like? Maybe leave the roof from the cab add a rolling bar(s). I was thinkin the suspensions must be different and if I don't convert a truck into a blazer without modified the suspension the body could maybe bed or crack.
