TL;DR Summary

Creating a tiny wavelength selectable light source using diffraction grating

Could a miniature wavelength selectable light source (lamp + monochromator) be created by using a broad spectrum led or tiny xenon/deuterium lamp as a light source combined with a small diffraction grating (and other necessary optics like mirrors, lenses)? Thinking of an application in spectrometry.

A broad spectrum LED and the xenon/deuterium lamp both have fairly discrete or peaky spectra. How continuous and smooth do you want this source to be?

Yes, but I suppose that depends on what you mean by "miniature" and what your "selectable wavelength" FWHM specification is.
