Have I selected the right funds after review of my Mutual Fund portfolio

I have good amount invested to HDFC TOP 200, HDFC Equity and HDFC Prudence over last 10 years. Would like to change this investment to following funds and remain invested for next 7 to 8 years. 1) change HDFC Top 200 to Birla Top 100, 2) HDFC Equity to Birla Equity Fund & Motilal Oswal Long Term Equity Fund, 3) HDFC Prudence to ICICI Balanced Fund and HDFC Balanced. Advise whether this is right move keeping in mind next 7 year investment. I am high risk investor and this is surplus amount?
