set priority to read lookup files

We have requirement to update main table (>30millions) based on business rules & lookup files. There are 46 lookup files with different schema & business rule. The priority to update is set for each lookup file & it need to done accordingly.
[table][tr][td]File Priority[/td]
[td]File Name[/td]
In this case the update will happen in order: AA,XX,BB,ZZ

The solution which we can think is:
Main Table -->(Lookup AA.txt)-->tMap1--->(Lookup XX.txt)-->tMap2--->(Lookup BB.txt)-->tMap3--->(Lookup ZZ.txt)-->tMap4--->so on...
Is this approach feasible? Whether it is achievable with one tMap?

Please suggest optimum development approach for this scenario.

Whether it's possible in Talend to set priority for lookup files?

read file(tFileInputDelimited) -> sort file (tSortRows) -> iterate over sorted rows (tFlowToIterate)
