Have the lift match the trailer specs and spacing along the number of bunks to the inch, and you should be fine 
I just installed 6 bunks on an AlumaHoist Lift. Made them match height and spacing of trailer. Materials ran about $600 for lots of good SS fittings, nylon washers and Aluminum brackets. First attemp with SS lag bolts to hold treated wood failed. Shifted to SS Carrage bolts and all went well. Be sure to double carpet over the Carrage bolts to prevent wear.
To get the right angle (same as deadrise of hull) I had to bolt brackets together in ONE hole > then set correct angle and insert 2 SS self tapping screws each pair of brackets. Pilot holes helped.
If you have a very good welder and access to a spare trailer - you could just canabalize the trailer and attach. Be sure your slip has sufficient depth as the bunked beams will be higher than the stock bunks on a lift.
My lift company wanted $3500 to build it. DIY with some buddies with good balance for losts less.
ps
do not drop power tools in water - and have a few extra nuts and bolts handy.

Here they are.
Will trim any excess board length and fully carpet soon (used 14' X 6" treated)
We'd love to see some pictures of your final product Searover if you have them.

Boar Lifts
I had modified my lift about 2 years ago duplicating the trailer set up. For the outermost boards I have used two 2 x 12 pressure treat boards with a 2 x 4 fasten to the top edge forming a Tee. The best way to get the angles is to make a plywood template of the trailer supports and use the template as a guide to space and align the 6 stringers on the lift. I have found that the 210 on the lift with a Covers, Inc cover works great for the full boating season.

lift fit
To get the exact angle / fit - I just left the bolts loose and floated the boat onto the boards. Lifted the boat slightly and marked the brackets. Removed boat - reset brackets; tightened bolts and inserted self tapping screws to lock it in.
I use the boat year round in South Florida.
