If that G5 iMac is running Leopard (10.5, the end of the road for PowerPC), then you should be able to clone that drive onto that Intel iMac and just boot it with everything staying exactly like it is.
You could boot the Intel iMac from a Leopard DVD, boot the G5 into Target Disk Mode, use Disk Utility from the install DVD to "Restore" the G5 volume onto the Intel iMac drive (if you select the option to erase the drive before the restore, it will be a very fast block mode copy).
