Perhaps, but even though Uryu's a prodigy and all that, the description of how the Letzt Stil works (pushing the body's ability to collect and manipulate Reishi way beyond its normal limits) seems to mean that any Quincy would become several times stronger by using it - and on top of that, Uryu used it back before he had Ginrei Kojaku and his stronger, more stable powers, which is a good indication of what a powerful Quincy like Quilge or Ryuken could do with it.
