Advice :- using loft for storage in timber frame house

I would like to use the loft for storage for sentimental items & the annual things like decorations, suitcases, etc. - Nothing heavy (if a little bulky!) Span would be about 2.5m from rafter to rafter & the length about 4.5m. Joists look like 3 x 2 at about 600mm centres. I do not want to add anymore insulation as the house is fine in winter & already gets to warm in the summer!

My plan would be to deck an area of the loft + a little more so it is easier to get around if dealing with any electrical faults or replacing the bathroom fan ducting for example

I have looked at the different options & have come up with
1) loftzone solution, but worried about the weight distribution at set points.

2) Sistering using 7x2 to run alongside the current joists, however as it is a timber frame house the span would be resting on an internal timber frame, which I am not sure is a good idea.

3) Screwing/gluing 3x2 on top of current joists & then cross battening with 4x2, but I dont see how that does anything better than the other solutions.

any advice?
