you can always install all you like and try to use it from within lxde desktop. if it works, let it be, if it doesnt and it doesnt take out on uninstall something else you want or imposes hi load on the system, take it out simply.
that way you ll get the lxde desktop with the applications you like which run on the hardware at hand.
the only thing is you have to do all by hand, since you need to test each application you want individually and have the synaptic package manager open all the time, so as soon as you rule out some as unwanted, it has to get out using synaptic.
