Wiring an alternator with kill switch...

I've never run an alternator on race only vehicle. I bought a 1 wire alternator to install on my current track only truck. I have a two pole shutoff switch on the back and am running dual batteries. Can I run a lead from the alternator directly to the starter to send power to the batteries instead of running the cable all the way back to the batteries? I have laid out below how I ran my wiring system because it's nothing like the factory had it. It worked great last season. I just wanted to save from having to charge between rounds.

I have 2/0 wire going from battery side of kill switch directly to the starter solenoid. I also have a 4 gauge wire feeding from the switched side of the kill switch to a power point in the cab near my electrical board. I also ran a 4 gauge from the power point to a firewall pass-thru to have a power source under the hood for the timing light, etc.

I'm using a floating ground system in my truck. Nothing is grounded to the body or frame. I have a 2/0 ground cable running to one of the starter bolts. I also have a 2/0 ground cable running into the cab to a ground block. I also ran a 4 gauge ground to a firewall pass-thru that allows me a point to tie in my cylinder head ground cables. Everything is grounded to the battery via the ground block in the cab.

Your thoughts would be appreciated.

I edited my question. Typing without thinking...

I have a dedicated power from the battery side of the kill switch (constant power) that feeds ONLY the starter. Basically what I need to know is if I hookup the hot lead from the alternator directly to the starter to charge the batteries will I have any problems with the starter, or the alternator?

if theres a direct and constantly connected copper wire connection between the single wire alternator output and the battery positive REGARDLESS, of if the solenoid is connected between the two , the alternator should charge the battery, with the engine spinning fast enough to generate current
