I had an interview for a postdoctoral position with a group with a big grant, who later rejected my application, the official reason being that "some [...] important aspects of [the project] might require intensive cooperation and supervision" and that "the supervision capacities of the PIs are limited" even though "[my] background [...] fits well to several of the research directions" and they were "overall positive about [my] application."
It so happens that the county in which one of these PIs is located has a call for individual postdoctoral grants. As is customary with these grants, I am to find a host that could support my application.
Would it make sense to write an application for this grant focusing on the aforementioned project's "research directions" to which "[my] background [...] fits well" with this PI? Assuming they were honest in conveying their evaluation to me, this idea seems somewhat reasonable, but I do not know if I can take their response at face value; it would a waste of time if they actually think that I am good for nothing.
