You are correct, you might not make the 2.5 climb requirement. This is why the procedure designers incorporate a level acceleration segment in the missed approach procedure. It starts at a minimum of 800'', 300 feet of obstacle clearance is provided and it is a minimum of 6nm long. If local conditions require a higher acceleration hight it will be indicated on the chart.
Hope this answers your question.
p.s. as the previous poster mentioned 800 is the minimum build in the procedure, nothing precludes you from doing it higher, Boeing indeed recommends 1000' as a minimum. My own company uses the missed approach altitude
