penning7, The first thing you need to determine is how do you usually fish? If you stand to fish or sit, the reason why is because once you inlet a section dedicated for the foot control unit, you are set in that area from then on. If you troll some times then maybe you would like to move the foot control unit a little to help accommodate that effort. :noidea: So it really depends on how you fish. If you always fish a certain way and a in-letted foot control section sound perfect, then by all means go for it.
If that is still your goal, then you need to look carefully up under the area you want to mount the in-floor control unit to make sure nothing is in the way and you have enough depth for it to fit correctly. If that all looks good, then either buy the inlet unit, or build your own. Then slip it in and make certain you have the capability for wiring and cable and even water drain outlet in and out of the area for the trolling motor connections and to allow water to drain out. So logistics and clearances are the key words here for it to fit and work correctly. JMHO
