Clone HD, But is Dual-Boot(Slave)

I have two separate hardDrives,Dual-Boot.....Primary(c:) is on a 40 gig(Windows 2k Pro)..
Slave is on a 80gig(windows XP Home).. I want to Clone the Windows XP to a 320 gig .I have two programs that will Clone ,Copy Commander 7 and Acronis which is on the XP.What I want to end up with is .......cloned Primary(c:)320gig,.....take out 40gig and use as a extra(somewhere else)
.........put "old"80gig(with " old original XP" in drive bay and leave it unhooked from power and EIDE cable for a Clone backup. My reason for doing this is to clone my HardDrive because it is about full and I NEED to keep my information.I want a large HardDrive with only ONE usable drive don't need win2k (older windows) ...Another Question is there going to be a problem with XP being the Slave originally?
