Once the hardware check's out of the way, the machine performs a software check: it spins up the CD-ROM, and looks at the region code information stored on the disc. If that information matches the information stored in the Mega-CD's BIOS, it will run the game as usual - if not, it will throw a tantrum and boot to the CD audio player screen.
It's this process the import carts will intercept; as the carts were created in Europe, I'd guess it will pass European region information to the console instead of the region data present on the disc. However, this process is slightly different for Mega-CD model numbers and board revisions - hence the hit and miss nature of the cart. It'll work with one CD console and not another - or maybe just one or two games on a specific board revision.
So to actually answer your question - no, it won't work. You have a European Mega Drive 1 and Mega-CD 2, I assume - if you keep the Mega Drive at stock 50Hz Overseas setting an insert an American disc, your machine will boot, but it'll refuse to run the game as it'll detect it's an American game from the CD's region info. If you set the Mega Drive to 60Hz Overseas as you suggest, the machine won't boot at all as it won't match hardware settings with the Mega-CD. Plus, it'll still fail the software test as the American game won't boot in an European console
There is a solution - use ConvSCD to change the region code present in an .iso or .bin. This means that you can inject European region information into an American game, meaning it will pass the software test. Hooray!
There is also an alternative solution floating around the net, called Multibios - this is apparently all three Mega-CD BIOSes on one chip, that you select with the flick of a switch. It goes on top of the regular Mega-CD BIOS - however, I've no experience with this as I'm too big a pansy to mess with the guts of my Mega-CD.
So yeah, two possible solutions.
HOWEVER
American and Japanese games are designed to be run at 60Hz. If you run it on a 50Hz Mega Drive & Mega-CD setup, the game may be glitchy - in the case of FMV-ish games, the audio and video will be out of sync. So, you have a 50Hz machine running a 60Hz-designed game 20% slower than it was intended to be run. How do you get it to run correctly, whilst still passing the hardware/software checks?
Simple. Boot the Mega Drive & Mega-CD in standard 50Hz mode. Assuming you've patched its region code, the game will spin up and load as usual, going to the Sonic 'dling-dling ... da-daaaaah' screen. At this point, set the machine to 60Hz. Problem solved yaaaay
There you go, Melf: one educational article for you =P
uhhhh, on-topic: cartoony games. Not like 'games based on popular animated series', I enjoy games that place gameplay experience over realism. Daytona USA's various incarnations are incredibly unrealistic, but I love it to bits anyway as it's fun. Same goes for OutRun 2006 for its absurd driftiness, Cave Story for its compelling plot and floaty physics, RKA for its cutesy exterior and hard-as-nails gameplay. Why worry about, say, which type of tyre is best for a particular racing track, or how much fuel I should put in my car, when I can scream round corners sideways in a Testarossa, hit a tree and somersault, and keep right on going? Realism may have a place, but I hate it when it becomes the central focus of the game. God forbid we have a Sonic game with animals akwardly standing in clothing and catching fleas, or a Mario game where the character has a heart attack after smashing his head into a brick too many times.
