What you are attempting to accomplish is called aggregation and YES you can combine multiple ISPs. There are commercially available 'appliances' that do this and are very expensive. AT&T Wireless Services provide this function for all Hilton Hotel properties.
Multiple Cable feeds, DSL and T1s can all be combined so that if one ISP fails the end-user will never see a broken connection.
There is software you can download and install on PC that will accomplish this.
You will need to have one ethernet card for each ISP plus one ethernet card to connect back into your local LAN. Effectively you will eliminate the DHCP services offered by any other routers in your LAN, since this 'appliance' will need to be providing this service for all connected system that you wish to offer aggregated band-width to.
