I have two different HDInsight deployments that I need to deploy. One of the HDInsight deployments uses the D12_v2 VM type and the second HDInishgt deployment uses the DS3_v2 VM type.
Although both the VM types use the same number of cores, would the deployments work if I just request a quota increase of the Dv2-series type? Do note that, at a time, only a single deployment will exist.

No, it won't work that way as both are of different VM series i.e. Dv2 and DSv2. So , even if they are using same cores , deployment will fail in that region if you don't have sufficient quota to allocate in your subscription for both of the VM series as it depends on your total Vcpu's available for that region.
You can refer this Microsoft Document for the VM series specifications.
So , as per your requirement ,You have to create the quota request for both the series in the particular region .
