In your case, you can definitely intrude the lower incisors, but will need to control the proclination through IPR and/or an IA followed by full-sized arch wires. Steel-ligating the stepped/torqued anterior segments fully secures the activation and minimizes unwanted flaring. 19x25 or 21x25 TMA wires allow for larger step bend activation like in the example below. I don't think you will have residual spaces, provided you have adequate axial control of the upper and lower incisors. The bite needs to be fully opened to permit retraction.
