yes, possibly.
Distribution amp is an option as is having multiple boxes. Doing switching off the LNB gives a lot of flexibility - but distribution of a couple of sat boxes giving two distinct channel options is another.

personally I'd get 19east Astra1 covered too - and certain boxes that accept softkeys like the Dreambox, TM1500, etc. But this means more expense....box-wise and LNB, switch, cable-wise.

You're looking at wiring anyway so the choice is prepare for distribution before or after decoding....
