One (count 'em one) of my friends did his dissociated tour with a MSRON about two or three years ago. I don't know the details of how he got there, if the billet was coded as a 1xxx, if PERS-41 and 43 made or horse trade, or if it was no big deal at all. Off the top of my head one of his peers at the job was a squared away LDO (prior enlisted MA) and others were various SWOs, so I got the idea he was bit of a fish out of water. I also think that him being there confused his first DH screen board because the detailer subsequently moved him to a more conventional nonflying billet before his second look.
FWIW.
Yeah, I can't speak for the MSRONs really, though I have heard secondhand of another aviator serving as an OPS, so maybe that's coded as a 13xx.
That said, going by the RIVRON AMD, the URL Billets are specifically for 1110 and 1140, and a 13xx obviously is very unlikely to fill a RL/LDO/WO billet. That plus the already small number of billets for officers...I wouldn't bet on it happening.
