Would you recommend investing in both Syfe's Core Balanced and Equity100 portfolios? I'm thinking of investing the same amount in the 2 portfolios using the dollar cost average strategy.

Syfe fees are based on AUM, which is the total sum of capital/value across all the Syfe portfolio you invested. So, it doesn't matter whether you have only 1 portfolio or multiple portfolios.

It is a good strategy to divide your portfolio into different time horizons with different expectation on returns. Your thought process for investing in both Core Balanced and Equity100 is sound, although you don't need to split your capital equally to the 2 portfolios. Since you want Core Balanced as a safety net (perhaps as emergency fund or certain big ticket planned expenses like wedding, housing, etc.), you can set a target amount and time horizon to build your Core Balanced portfolio, and channel the rest to Equity100.
