As part of the AO-related upgrades envisioned for the Gemini Observatory a feasibility study has been started aiming to integrate GeMS with Flamingos-2 operations. This latter, hereafter referred to as F2, is a wide-field near-infrared imager, long-slit and multi-object spectrograph with a demand contribution among the Gemini South instruments currently ranging around 15-20%. The integration with GeMS can open the possibility for an AO-corrected beam to feed spectroscopic modes, thus significantly increasing the sensitivity and spatial resolution of F2 observations covering J, H and K bands. First steps towards this goal included a characterization of the current PSF centroid stability delivered by GeMS using the Gemini South Adaptive Optics Imager (GSAOI), followed by actual tests with the GeMS+F2 setup. A brief presentation of main aspects and challenges being addressed in this feasibility study is given, such as related to calibration issues, a revisit of the non-common path aberrations calibration strategy, background contribution and field distortion characterization. Results from preliminary operational settings and on-sky tests are presented.
