If you calculate the deflection, it will be the same as for 1.2m and 21mm råspont if you choose 1.8m and 32mm. The deflection is proportional to the span raised to the power of 3 and inversely proportional to the wood thickness raised to the power of 3. Whether the trusses can handle it is another matter, as mentioned earlier.
