Some kind of integration will always be needed.
If you cannot use an RC integrator, use a DAC and a up/down counter.
As your input signal is high, count upwards high frequency pulses. When the input signal is low, count downwards. The output of the counter is supplied to a DAC. A low-pass filter smoothes the DAC output.
Another way could b

The input sinewave may have varying frequencies. Would there be a problem if we convert it into square wave and take integral? I tend to believe that the resulting triangular wave would have varying amplitude
Yes, you are right. The result of integration depends in its amplitude on the duration of the (...)
