Nope.
I've used the idiom <"_1 |: before with success, but I think in a
different context; in any case when modifying your code I didn't even notice
the LHS.
So how about this?
(, {.data) =. , (<@:,;.1~ a: , (<1) #~ _1 + #@:$) }. data
This time, I did test:
nms =: {&.:(;: :.;&.>)'a b c';'d e f'
dta =: <"0 i. 3 3 3
data =: nms,dta
(, {.data) =. , (<@:,;.1~ a: , (<1) #~ _1 + #@:$) }. data

The only real wart is those final ravels. They're necessary because the LHS
and RHA must agree in shape, and multidimensional LHA are prohibited
(probably specifically because of this assignment-opens issue).
