boarding loft over binders

[valhior]

hello all
i want to board my loft. across it i have 4 binders (two middle 4x4 and two 4x2) on top of celling binders whith are 4x2
these binders are little in my way with boarding, so i was thinking to add another 4x2 joists on top of them (with will give me nice 300mm space for isulation)
I don't want to put new joists from wall to wall across loft, because this is to big distance
so, my question is, if that will be ok, to board flor over binders, with all weight sitting on them (any way i won't store there alot)
Thank you for ansfers
