It is definitely feasible.  Most protcols that I have seen which deals
with cDNA do not use ligation of adapters to double-stranded cDNA
perhaps due to the problem of loss of 5' sequences.  Most involve
tailing reactions, but one recent one use RNA ligase.  References

whether this approach could work on a heterogeneous population of
