I think you definitely should!
I'm not sure about the 411, but the Poly engine in the early V8s has the distributor at the rear of the block so I don't think interference would be a big issue. Ford engines with the distributor right next to the ECU seemed to be the worst offenders.
The big issue for me was the number of reports of failed ECU on the original Sniper. I very much hope version 2 is more rugged. V2 also supposedly has improved throttle geometry.
The main reason I am considering a Sniper is that fitting overdrive brings the engine speed so low at motorway cruising speeds that a standard distributor doesn't have the timing range to cope. Also the Weiand inlet manifold that I have presents mixture issues at low RPM that are hard to accommodate with a standard carb and distributor. These are both marginal issues but adding a Holley Hyperspark controlled by the Sniper should bring everything into line. Add a decent tubular manifold with ceramic coating and I very much hope to have an original engine and nearly original transmission with the drivability and economy of much more recent cars.
