I know that you can get plates which are designed to take 1, 2 or 4 fermenters.
Or do you want something that can deal with colder temps rather than more fermenters (now you have less)

I assume you're talking aquarium heaters - I can be quite thick this early in the day...
If so take a look here http://www.aquatics-online.co.uk/catalo ... cables.asp
The Jäger range is quite good - efficient and the temperature setting will go down to 18C, often 22C is the minimum.
Could try wrapping a layer or two of foil bubblewrap insulation around the fermenter, held in place with a bungee straps, then use a smaller wattage heater. O.K., so it's less high tech than your power controller...
In the dim and distant past when I was last homebrewing I built a simple cupboard out of chipboard, insulated on the inside with 2 inch polystyrene slab. Then a slatted shelf at the bottom for the fermenters to stand on, beneath which were a couple of 180-200W (? - quite low anyway) tubular heaters. The heaters being controlled directly by an old central heating room thermostat fitted about two thirds the way up the cabinet. Used that in an unheated shed without any problems, maintained the ambient temperature in the cupboard quite well after initially getting the 'stat set correctly.

Another quick thought - I'm fairly certain that the Jäger heaters have electronic temp control, rather than a simple bi-metal thermostat, and may be unsuitable for use with your power controller. Probably a good idea to contact the manufacturers first to check - http://www.eheim.de/eheim/inhalte/index.jsp?id=24868
The inbuilt thermostats top end setting is 34C - unless you could disable that I don't see how you would use it in a mash tun.
