On my completed Lunatic run, I didn't use Wireless stuff until after Ch17. Based on my incomplete Lunatic+ run, I get the impression that taking into account better skills to fix the many things I failed at in that run, including skills I had picked up by the time I finished it, I'd say Lunatic+ is just as doable for an appropriately more-skilled player. So yes, it should be workable.
Not that I'm tackling that just yet. I'm using Wireless stuff freely off the bat in my second, regular Lunatic run, and I plan to do the same for the Lunatic+ run I actually complete afterwards. I do intend to try something like this, but not until a few playthroughs later, when I've also played all the way through Lunatic under the same conditions.
