DO letter of rec question

I'm applying this cycle and am having a really difficult time finding physicians to shadow/get letters of recommendation from. Many of the schools I want to apply to require a letter from an MD/DO. I reached out to one DO who is willing to meet with me (but no shadowing). Would it be inappropriate to explain my predicament and ask for a letter of recommendation?
