Keifer Moore is maybe available I'd heard. If the plan B is a Crooks sized player then he'd maybe be a good option. I think (although Carrick seems to disagree) that Forss could be the smaller/quicker/direct option to rotate in and out with Lath as required, with Jones / Silvera covering the right.
I do think a big part of our current issues is that the ball isn't sticking much anywhere currently, so we're constantly on the go and getting over run. Archer and Akpom held the ball and occupied the defence much better than the current options are.
Although Moore doesn’t fit what I'd perceive our style to be, Carrick seems to have been more than happy to use Crooks up top when he's had plenty of other options. I think Moore would be an enormous upgrade on Crooks/Coburn/Muniz in that role.
But whether he's actually available, affordable and would come for a (probable) rotation role seems pretty unlikely.
