Is it okay to convert bam files to fastq and then getting seqkit results?

Question

[Baran]

I'm sorry if this is a non-sense question but I am a rookie and although I searched about this I couldn't find any decent answer. I had the fastq files but they somehow became corrupted. I need to get Q20 Q30 scores for the fastq file but I only have bam files right now. So, I wonder if it is okay to get fastq files by converting bam files with the gatk SamToFastq convert function and then getting the Seqkit stat results?

That sounds reasonable to me ;)! Quality scores are preserved when converting from BAM to FASTQ.
