I personally would love to see an online version of the console rpg makers (including those that were never released stateside), but I highly doubt that will ever happen do to the fact that they were made by another company (not Enterbrain) and would require a lot of extra coding to make them useable online versus a console.
However, I'd even settle for playing a console game made with RM, but that's also very near impossible without jumping through hoops. You could go to the RPG Maker Pavilion to see if you can find an answer (http://www.rpgmpavilion.com/), but as others have commented, it's just too much of a hassle. Looking at that website, it appears you'll need software capable of uploading the game, and players will need software that enables them to play the game, as it will probably need to emulate the PS1/2 controls. Whereas with online versions of RM, the player only needs to download the RTP and then can have access to almost any game available from RM2K through RMVXA. A lot of these people looking to play a game will not have the know-how, patience, or capability to get console games to work on their PC, which diminishes your target audience tremendously.
