The phrase "mostly mutually exclusive" is grammatically correct and can be used in written English.
It is often used to describe two things that are mostly separate or incompatible with each other.

While diet alone led to weight loss, exercise alone did not have a significant impact on weight but did improve overall fitness levels."
Interestingly, none of those who said they had a lack of time/motivation also mentioned a lack of need in their comment, suggesting these reasons could be seen as mostly mutually exclusive in our case.
Using a maximum likelihood statistical method, chromosomes affected by MSG or SR and likely to represent changes that are selected for during tumor progression were found to be different and mostly mutually exclusive.
The outstanding features are that missegregation and structural rearrangements lead to chromosomal imbalances that are mostly mutually exclusive and combine to generate CIN in almost all tumors tested, suggesting that chromosomal disorders generated by MSG and SRs might have complementary rather than additive effects in CRCs.
Furthermore, similar to the proceeding time points, γH2AX staining remained mostly mutually exclusive from the foci of CENP-A.
In papillary thyroid carcinomas, BRAF mutations, RET/PTC rearrangements, and RAS mutations are mostly mutually exclusive [ 3].
In Drosophila, genomic data indicates that translationally optimal codons and splice optimal codons are mostly mutually exclusive, and adaptation to translational efficiency is reduced in the intron-exon boundary regions where potential exonic splicing enhancers (ESEs) reside.
Both EFL and eEF1A are present in all major lineages of eukaryotes, and their presence is mostly – but not universally – mutually exclusive, as previously reported [ 11].
Interestingly, within this subtype of GBMs, PDGFRA amplifications and PIK3CA/PIK3R1 mutations (leading to constitutively active PI3K subunits p110 and p85, respectively) mostly occur in a mutually exclusive manner [99], signifying an overlapping functionality between these two alterations in gliomagenesis.
