This approach is the most convenient and less expensive option. Further saving can be made by reducing tagmentation reactions to 1/4 of Illumina recommendation for Nextera XT. In this case PCR volume still need to be 25 or 50 ul to have optimum yield. When using full contents of the kit, PCR can be done with KAPA HiFi polymerase in 25 or 50 ul volume.
