Its very hard to give pointed advice just based on your 3 sentence question. Broadly, if you tick the boxes- good experience to demonstrate consulting skills, CV, referral etc then I dont see why moving to MBB/T2 will be a problem. I have seen many people in my network do this.
But, please beware- dont make decisions now with some future event in mind. The KPMG Ops role must fit with your career aspirations & values NOW otherwise you are going to hate it. Similarly, any other path/job you choose to pursue needs to FIT. Only then you can give your best, enjoy your work and create the path towards MBB/T2.
