Try to make your device modular and use one NXT per module. This is easier to build, develop and test and thus, more fun. Use as many motors in a module as you need. But don't forget to look at other possibilities as well. Gearboxes can be used to drive different functional parts, but only one at a time. Touch sensors or light sensors can replace tacho's sometimes.
Connect the modules over a network. RS485 seems the best solution for time synchronized networks. While you have two NXTs you don't even have to use custom cabling (I guess).

Hi,

great advices, thank you all.

In the meantime, I purchased 2 more NXT bricks which gives me more freedom, but doesn't make it more easy.

I think I will now, setup a RS485 network, and use motor multiplexers on each port, this must do the job. Once I get it running, I hope being able to get back in here and share my experiences with you.

Didn't see this mentioned, however did see that you mentioned you had some XL Motors.
