Will the LS7 Dry Sump Pump and Pan fit other LSx engines? Let's say we wanted to go road racing (or track days). We really didn't care if the car has 390 or 450hp. However we really do care that there is oil in the main gallery going around the Carosel at Summit Point or the Big Bend at Lime Rock.
Could the presumably inexpensive pump/pan/front cover be installed on other LSx engines?
Generally, in addition to being expensive, aftermarket dry sumps require an external pump and hoses that have no where to go. At least with PS and AC in place. For a real race car we would something that also pulls some vacuum, however here, positive oil pressure is the only issue.
Yes, an Accusump is an option. However, a dry sump is much more elegant.

IMO, I see no reason why you couldn't use the LS7 factory dry sump setup on any LSx engine. From disassembling the engine here is what I gather you would need to retro.
1) LS7 factory 4" crank with its longer snout or an aftermarket piece with your choice of stroke incorporating the long snout.
2) LS7 lower timing chain sprocket.
3) LS7 dual rotor oil pump.
4) LS7 windage tray / pan assembly.
5) LS7 front cover... currently only needing adaptor harness for LS2/LS7 blocks only.
5a) Currently only needing 1x (early LS2 style) cam sprocket for 24x reluctor wheel setup OR 4x (late LS2 and LS7 style) cam sprocket for 58x reluctor wheel setup for LS2/LS7 blocks only.
6) LS7 harmonic balancer for C5/C6 accessory drive alignment OR aftermarket balancer, yet to be supported by known manu's, with correct offset for anything other than C5/C6 accessory drive.
7) Folks are finalizing adaptation from pan to either factory LS7 tank or aftermarket depending on vehicle application. Details forthcoming...
8) LS1 edit removal of oil level monitor.
That should cover it... maybe a few small details I missed...
