Daisy Chaining Multiswitches?

Greetings everyone -
I have an existing DTV system, with two coax from the antenna. I have a multiswitch to split it to two DTV (dual tuner) receivers.

I want to switch one receiver to a HD (dual tuner) receiver.

I know that the new antenna requires four coax cables. But I cannot run an additional 2 cables to where my receivers are.

Here is what I think might work, and I need someone to tell me for sure:
In the attic, install a new multiswitch. From this, take two output cables and run to where my receivers are, then add a second multiswitch to connect to the two receivers.

Will that work? If not - what can I do short of running new cables all the way down to the receivers?

Thanks!
dan

No, this will not work.
The new dish, the 5-lnb, has four outputs. You will have one dual-tuner SD DVR, and one two-tuner HD DVR, correct? You will need to run two cables from the dish to each DVR, no multiswitches. Or you can run four cables from the dish to where you currently have your 2x4 multiswitch, replace the 2x4 multiswitch with a Zinwell 6x8.

Each tuner has to have a dedicated path back to the dish so it can tell the dish which set of transponders it wants to see. There are four possible options so a multiswitch with four connections to the dish can connect any number of tuners, it just connects the tuner to the right one of the four.
Connecting only two cables means that the receivers will not be able to see any of the 103/110/119 satellites (all the new HD is on 103)
