Wellll, "is it viable?" is kind of a loaded question. Turbine hasn't done anything to nerf bardchers per se in the last couple of years; but throwing weapons (Swashbuckler) and xbows (Mechanic) got major buffs in the last year, which makes bardchers look weaker by comparison - and to be honest they weren't that great compared to monkchers in the first place.
Which is why my bardcher builds are still ranged/melee hybrids.
Meanwhile the latest FotM in monkchers is the monk 6 / pal 14 split because Holy Sword boosts longbows into 19-20/x4 weapons which is doubled by IC:Ranged to 17-20/x4 (Pinion is 15-20/x4). That plus all the other ranged bonuses associated with monkchers makes them pretty formidable.
That said, it also depends on what you see as the primary function(s) of this build. If you want to focus on ranged DPS, bardcher's not the best way to go, unfortunately. OTOH, if you see yourself as a party support toon which uses a bow, bardcher is...well, no worse than it used to be, anyway.
