Megadrive Saturn Dreamcast to 1 LCD Solution

[THE EQUIN0X]

Hi all!
My crt has to go unfortunately. Not enough space an with my baby due in less then 3 weeks I'm finally seeing sense.
Anyway I've picked up a few of the retro consoles I used to have when I was a kid an give some love via modding and cleaning and now ready to set up to my vga led screen.
I'll give you my setup and just after ideas if it's my best option/setup or not.

Asian 1 Megadrive (50/60 region switch) > RGB scart > gbs8220 > vgacable to 3way splitter

Pal Saturn (50/60, mod chip, pal/ntscj/ntscu ) > RGB Scart w/sync cleaner > gbs8220 >3way splitter

Dreamcast pal > vga box > 3way splitter

Vga from splitter > slg3000 > finally connect to telly

Hope whoever is still awake can help. I've missed out the 2-1 Scart switch ( for megadrive/Saturn) as well before the gbs8220

Do I need the Scart sync strike still as well

Many thanks

Mike

also can the RGBS and Gr be of any use in the above set up, I'm guessing that it is a clean sync connection
