I've done that before with a CO's approval for a twice daily message, we just included a note in one that we would consolidate the twice daily update to the morning one. No one noticed for about 5 weeks at CJOC, but they also had no idea we were sitting off the coast of Syria within range of their shore battery and about a mile away from the Russian carrier doing bombing runs on locals, and thought we were on a NATO booze cruise so that victory felt a bit hollow. Still, one less daily message to generate was a plus!
In this particular case we needed approval to go to the next round of SBCA (directors at CAF, PSPC and ISED to DGs at each) so that wasn't an option, and the whole thing was a mandatory approval gate (with 4 or 5 sub gates) to move onto RFP release, which still actually hasn't happened. It's just to buy some COTs gear, that meets a commercial standard, and then maintain it, for possibly it's lifespan (15 years) with options for a bit of maintainer training etc, so actually really straight forward.
This may have been the particular straw that made me want to never be posted back into ADM(Mat) ever, as it was just so stupid with zero value added. I'd kind of love to shift over to an auditor job for a bit to look at things like this to see what impact the significant delays had on actual outcomes, and what the real costs to delaying the project were. In this case, it was probably $3-4M for a project worth about $30-35M (depending on some inflation, wear and tear and maintenance projections).
