Yes it is but you need to contact structural engineer for drawing as this is structural thing which needs professional designing

Joining steel beams together is usually done by bolting or welding. Determine whether or not the steel beams you are using need to be welded or bolted. ... Fabricate a splice plate that allows the two steel beams to be joined together. The splice plate is usually a steel plate of a given uniform thickness. This will have to be approved by a structural engineer and additional calculations may be necessary. Steve .

You definitely need to get structural calculations done before you proceed to see if the steels are up to the job

Yes great answer your first protocol is to contact a structural engineer to determine the calculations you require.

The answer isn’t incorrect but existing beams to new beams would need to be overlapped by probably around a metre and would have to be double bolted through

No not advisable, the beams have probably been sized ( by calculations) to suit the span of the opening and carry the load above, a wider opening crates a bigger load so therefore needs a larger beam. structural engineer required to do calculations.
