With the additions of Campos, and El-Khalifi barring visa issues, KIR has learned that there is still a chance of a 3rd addition. RSL GM Garth Lagerwey mentioned that it's a "possibility", but also indicated that they wouldn't rush out and do something. So I would expect something more likely toward the end of the transfer period.
Lagerwey also mentioned that it's not likely to be an attacking player. The focus will be on a versatile player, likely with an emphasis in helping in the back. A defender/midfielder combo would be a good fit, as with the departure of Joy and these recent additions the numbers have swung in favor of the attacking portion of the squad and if there is a need for roster depth it is defensively.
