  Searches for neutrinoless double-beta decay continue to expand our
understanding of the lepton sector, with experiments now pursuing ton-scale
target masses with sensitivity to $m_{\beta\beta}$ covering the allowed
parameter space for the inverted neutrino mass ordering. Continued searches for
this rare decay will require scalable detector technologies to achieve
significant increases in the target mass beyond the ton scale, in order to
probe the normal ordering region. This work explores the concept of searching
for neutrinoless double-beta decay in a 10 kton scale liquid argon time
projection chamber (LArTPC) located deep underground and doped with
percent-level quantities of xenon. We discuss the design requirements,
background mitigation and detector R&D needs, and considerations for deployment
in a modified DUNE far detector module. We find that such a detector could
reach $m_{\beta\beta}$ sensitivity at the 2-4 meV range with xenon doping at 2%
if significant background reductions can be achieved.
