Take a look at the Pocket Wizard MultiMax units if you have not already done so. These units give you four remote groups (A, B, C, D) plus one on-camera called L, for Local.
With these units, you can produce timed interval shots a couple different ways, with intervals in the hours if required. I've had a bit of fun experimenting with a half dozen of these units firing at 0.0, 1.5, 4.0 and 8.0 seconds after shutter opening. Following initial setup of the remote units, all control of which groups will fire is done at the on-camera unit. Yes, PWS will fire a pair of speedlights from each unit, so long as they are identical and do not have excessively high trigger voltages (>250 volts according to the manual)
Current PW range is given as 1,600 feet, absent any thick concrete walls, metal buildings, etc. I've not tested this yet, but it is certainly much greater than the optical CLS, which I have fired at night in excess of sixty feet or more.
Thanks for your comments.
