Gave this some thought. A steel front triangle or aluminum with a straight seat tube .  Two halves of plate machined for bearings and a machined center channel that mates to seat tube. Clamshell the two halves and bolt around seat tube.  These are your adjustable pivot points to mate whatever rear suspension tickles your fancy. Cost for machining 4 pieces of bar stock. It could be done manually or simple CAD design.  I'm guessing about 500$ for the machined parts as it's a very easy process with few cutting steps.   Cascade components ? Makes after market links for Suspension.  Link mods are done with a newly married  part machined by a second party.   Personally I like the idea of saving frames from going into the trash. Mate the two good halves together.   I used to own a lathe. I really wish I had space and money/ time to run a small cnc milling machine .   Yes with Renolds top notch steel tubing you can or as Andrew points out the better material stainless steel. You can make a front triangle about 4 pounds or 2 kgs no problem. Mate this to a spesh carbon fiber read end with said link mods.   Weld on shock mounts and you . Spent a lot of money lol.  But it would be my custom bike . BTW is it impossible to buy rear ends from bike companies? Don't they keep spare front triangles and rears for warranty issue s or do they take apart existing frames. ?
