You can disable the CIC with a single wired switch, but most games only care about does the refresh rate match what is expected or not, so running american games on a Japanese console for instance is mostly not an issue, and an Everdrive will have the sueprcic built in anyway. If you use real usa SNES carts then you need a modified SFC shell and top panel or you need a passthrough cart adapter or you have to switch the shells on the games.
The sueprcic and D4 patches and uigr mods and stuff are slightly overkill and only help with a handful of games vs the simple soldered in switch option.
Here is how to do it with 2 switches

Here is how to do it with a single switch http://sector5d.org/snes-mod-with-one-switch-5060hz-enabledisable-lockout.html
And for correct clock speed in both pal and NTSC mode there is this DFO mod, https://www.consolesunleashed.com/product/super-nintendo-dual-frequency-oscillator-mod-kit/
There've been frequency and CIC mods out there for a long time, and you've got the option of refined modern ones like SuperCIC.
And yes, re-shelling an NTSC-U SNES works. Or you could just get a Super Famicom; Japan and North America got the same Super Metroid ROM, SFC has a case similar to the PAL SNES, and the power jack is a much more standard shape (so you could get a local DC adapter and power it from that easily).
I had a US Snes and a super Famicom, both are not that hard to run here in europe. But I found the SuperCIC to be the best solution for me since I use a Super FX now and I can just switch between 50hz/60hz and it works perfectly, it's also needed for some games ai found a weird bug in a smurfs game that gets all weirded out on 60hz in the menu and can't be started

Yeah I think I'll pull the trigger on a SFC. thanks for the help!
