my 3-way switch is wired this way, because i am unlucky:
so i have neutral in the line box, no neutral in the load box. i want to use a leviton smart switch that requires neutral in both boxes. if i were crafty enough, could i pigtail a new line off the neutral line in the fixture to run down to the load box? i am super green at this, so forgive me for asking a stupid question. there's also some information out there saying i can use one of the travelers as neutral, which i'll try first… i'm just playing 'worst case scenario'.

Your problem isn't what you think it is
Getting neutral down to the load-side switch for the remote (DD00R-DL) used with your dimmer (Leviton DW6HD-1BZ) is easy enough; the white wire in the existing cable can simply be un-redesignated (if it was taped in the first place), then moved over to the neutral junction in the light fixture box.
However, this isn't what's stopping you from installing your dimmer. Your problem is that the DD00R-DL remote needs line-hot, a signal wire, and a neutral; however, the incoming hot is only available at the line-side switch box in your setup. So, you'll have to re-run one of the cables with /4 instead of /3 (or an ENT with THHNs in it) if you want to use this dimmer, or use different hardware that can work with the remote being on the load-side of the setup instead of the line-side.
