with what you have built, if it's "universal" enough, someone with an older boat can pop it on the boat and if there's a slightly larger gap between platform and boat it's not going to be a dealbreaker vs the alternatives above. mount to the brackets and who cares if the gap is 1/2" at the edges and 1.5" in the middle from the transom. no one will ever care. downside would be splash from water coming up but a stiff piece of rubber screwed to the bottom trimmed along the edge of the boat will stop any and clean up the gaps.
that was my original comment in keeping it a somewhat universal size AND making the bracket area on the underside wide enough to be used on a variety of different bracket widths from different manufacturers. even within the supra lines I would think that the 20ssv and 21v bracket spacing is different due to the boats being different widths.
the only downside would be shipping. cost will be quite a bit to ship it.
