I went from a 5" Down Image unit to a 7" Down Image unit ... then added the Garmin 93sv (w/o tdx) & Livescope. Yep, bypassed the Side View technology completely, and don't feel a bit of remorse for doing so. IMHO ... SV isn't for me & my way of fishing, so when I had Brian @BBGmarine put a combo together for me I had him leave out the transducer for the Garmin 93sv unit in the deal.
I already had my 7" DI unit tdx on the bottom of the TM, so adding the LS tdx to the shaft posed no problems. The Garmin unit is for LS only, and I use the DI unit for maps/waypoints.
Total output for the Garmin, Livescope, mount for Garmin unit, & a dedicated battery for the Livescope/Garmin setup ... $2500 (as of a couple of years ago) -- Garmin unit/LS - $2200 + mount $100 + battery 68ah AGM $200
You might even get a better deal nowadays, so if I were looking for new electronics today ... I'd check sale prices & compare them against what price Brian@BBGmarine (member sponsor classifieds) offers and see which deal is best.
