Stitching read pair R1 andf R2 sequences based on alignment from SAM/BAM

[mmokrejs]

Hi,
there are many tools (bbmerge.sh from BBmap, VSEARCH, USEARCH, ...) which can look for some overlap between members of a FASTA/Q read pair but is there a tool which can use already mapped pair memebers to a common reference and merge them? I have the .fastq.gz files still around so it could maybe just act on position-sorted SAM/BAM and poke through the synced read pairs in R1 and R2 files and merge them accordingly (replace Ns with a nucleotide from the other mate, eventually prefer higher QUAL)?
